ALSA: core: Fix randconfig build wrt CONFIG_PROC_FS

2015-05-29T05:21:02+00:00

There are a few leftover CONFIG_PROC_FS forgotten to replace with
CONFIG_SND_PROC_FS.

ALSA: replace CONFIG_PROC_FS with CONFIG_SND_PROC_FS

2015-05-27T19:25:19+00:00

We may disable proc fs only for sound part, to reduce ALSA
memory footprint. So add CONFIG_SND_PROC_FS and replace the
old CONFIG_PROC_FSs in alsa code.

With sound proc fs disabled, we can save about 9KB memory
size on X86_64 platform.

ALSA: seq: Fix init order of snd_seq_device stuff

2015-03-11T11:53:52+00:00

When the sequencer driver is built in kernel, it may panic at boot
because of the uninitialized snd_seq_bus_type.  Initialize it properly
via subsys_initcall() instead of module_init() to assure that the bus
is registered beforehand.

ALSA: seq: Drop snd_seq_autoload_lock() and _unlock()

2015-02-12T13:42:31+00:00

The autoload lock became already superfluous due to the recent rework
of autoload code.  Let's drop them now.  This allows us to simplify a
few codes nicely.

ALSA: seq: Define driver object in each driver

2015-02-12T13:15:54+00:00

This patch moves the driver object initialization and allocation to
each driver's module init/exit code like other normal drivers.  The
snd_seq_driver struct is now published in seq_device.h, and each
driver is responsible to define it with proper driver attributes
(name, probe and remove) with snd_seq_driver specific attributes as id
and argsize fields.  The helper functions snd_seq_driver_register(),
snd_seq_driver_unregister() and module_snd_seq_driver() are used for
simplifying codes.

ALSA: seq: Clean up device and driver structs

2015-02-12T13:13:47+00:00

Use const string pointer instead of copying the id string to each
object.  Also drop the status and list fields of snd_seq_device struct
that are no longer used.

ALSA: seq: Rewrite sequencer device binding with standard bus

2015-02-12T10:35:11+00:00

We've used the old house-made code for binding the sequencer device
and driver.  This can be far better implemented with the standard
bus nowadays.

This patch refactors the whole sequencer binding code with the bus
/sys/bus/snd_seq.  The devices appear as id-card-device on this bus
and are bound with the drivers corresponding to the given id like the
former implementation.  The module autoload is also kept like before.

There is no change in API functions by this patch, and almost all
transitions are kept inside seq_device.c.  The proc file output will
change slightly but kept compatible as much as possible.

Further integration works will follow in later patches.

Subject: ALSA: seq: Remove autoload locks in driver registration

2014-10-18T18:25:19+00:00

Since we're calling request_module() asynchronously now, we can get
rid of the autoload lock in snd_seq_device_register_driver(), as well
as in the snd-seq driver registration itself.  This enables the
automatic loading of dependent sequencer modules, such as
snd-seq-virmidi from snd-emu10k1-synth.
